I’ve never tried Boost, but I’ve tried a majority of the major brands and a few lesser known ones. When I drink a whole 16oz can, I feel nothing. Literally. The only way I even feel the slightest bit of “boost” is when I chug down a can on an empty stomach.
I think this is because I’m desensitized to them. When I first started drinking them, they were awesome. I remember one time I drank one before I took a final exam on an empty stomach, and after the exam I was walking back to my car. I could barely squeeze in my steps. I was so exhausted. I felt like I ran 10 miles. I was out of breath from walking and I felt like fainting. I had to sit down to recover, and I was also starving. I think it’s a terrible mix of the sugar crash, hunger, mental exhaustion, and lack of sleep from the night before. However, I didn’t feel any actual boost during the test (except maybe for some twitching)...but the aftereffects, I felt them like crazy.
Now when I drink them…I just think of them as vitamin B supplements…
